En las últimas décadas, los ciberataques se han convertido en una de las formas más comunes de reducir deliberadamente la fiabilidad de los sistemas en red. Un tipo habitual de ciberataques son los llamados ataques de engaño, que pueden incluir mediciones o entradas de control incorrectas, marcas de tiempo erróneas o una identidad falsa del dispositivo emisor. Este trabajo aborda el problema de filtrado fusión distribuido de señales en tiempo discreto a partir de medidas proporcionadas por diferentes sensores susceptibles de sufrir ataques de engaño que inyectan información falsa modificando aleatoriamente las medidas reales de los sensores. Utilizando tales medidas y mediante un tratamiento por innovaciones, en cada sensor, se calculan filtros locales lineales de mínimos cuadrados y, seguidamente, estos estimadores son fusionados para obtener el filtro distribuido propuesto mediante la combinación lineal óptima, ponderada por matrices, que minimiza el error cuadrático medio.

Keywords: Redes de sensores, estimación fusión distribuida, ataques de engaño
